Abstract
A propeller turn-over device comprises an upper bracket, a lower bracket, a middle shaft and a nut. The middle shaft is fixedly connected with the lower bracket at the bottom thereof. The upper part of the middle shaft is wedge-shaped, and the screw thread is disposed on a disk portion and matched with the nut; upper and lower lifting eyes are respectively disposed at the top and the bottom ends of the middle shaft; a shaped circle hole matched with the wedge-shaped part of the middle shaft is disposed in the middle of the upper bracket which is sleeved on the wedge-shaped part through the shaped circle hole; and the nut is on the middle shaft and pressed tightly on the upper bracket through a gasket to form the propeller turn-over device. A propeller is assembled into the upper and the lower brackets and pressed using the nut, and can not be contact with the sling when slinging for turn-over; therefore the damage to a blade and cut-off of the sling are thoroughly prevented. The devicechanges the original propeller turn-over lifting method, and is an innovative technique modification for turn-over of the blade, and of high practical value for batch shipbuilding and specialized shipbuilding.
Description
Technical field
The present invention relates to overhead hoist, particularly relate to the marine propeller equipment for supporting patient with burn.
Background technology
In ship building, screw propeller is before installation is gone on board, all to carry out bedding-in to the blade on its positive and negative two sides, at this moment just need through lifting, with screw-propeller turning-over, before the lifting screw propeller, way in the past is that screw propeller part of the force (generally near the prop shaft hole) wrapped it with copper sheet, rubber skin, ox-hide, uses hoist cable (steel rope or nylon sling) that its locking is sling, stood up then.Though taked various countrmeasures, draw phenomenon curling, that tear apart or hoist cable is cut off to take place propeller blade but still have, the personal safety accident is scrapped and taken place to the very easy screw propeller that causes, in the case, need a kind of safe and reliable screw-propeller turning-over device to guarantee quality and the personal security that blade stands up.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of screw propeller guarantees safety in production in the bedding-in process screw-propeller turning-over device.
The technical scheme that adopts is:
Screw-propeller turning-over device comprises bracket, bottom bracket, tween drive shaft, nut.Described tween drive shaft is captiveed joint with bottom bracket with its bottom, tween drive shaft top is made wedge-like and is provided with screw thread in disc portion, this screw thread and nut match, the top of tween drive shaft and bottom are respectively equipped with hanger and following hanger, described bracket middle part is provided with the shaping ring hole that is complementary with tween drive shaft wedge-like position, bracket is contained in wedge-like position on the tween drive shaft with its shaping ring borehole jack, and nut is spun on the tween drive shaft and by packing ring and is pressed on the bracket, constitutes screw-propeller turning-over device.
The above-mentioned bracket and the two side ends of bottom bracket are equipped with the hoist cable banking stop, and the hoist cable banking stop is provided with the hoist cable corner protector.
The present invention packs screw propeller up and down into behind the carriage, use nut compressing, slings that hoist cable does not contact screw propeller when standing up, and has thoroughly removed the phenomenon that damage that blade is produced and generation hoist cable cut off, and has changed original screw-propeller turning-over hanging method.
